LIGHTING FIXTURE.

Application filed Eune 28, 1923.

To aZZ whom it may concern:

Be it known that I, FREDERICK W. WAKE FIELD, a citizen of the United States, and a resident of Vermilion, county of Erie and State of Ohio, have invented a new and useful Improvement in Lighting Fixtures, of which the following is a specification, the principle of the invention being herein ex plained and the best mode in which I have contemplated applying that principle, so as to distinguish it from other inventions.

The present invention relates to lighting fixtures and more particularly to a globe holder such as uses a chain support. In fixtures of this type, considerable difiiculty has been found in making the globe and fixture hang vertical as the heavy globes do not run even and 'one sideis often heavier than the other. The present globe holder is therefore so constructed that added weight may be in serted around the outer edge of the holder to compensate for uneven weighting of the globe. The holder is so arranged that the weight may easily be added when the fixture is put up and the weight may be changed as to amount or relative position. To the accomplishment of the foregoing and related ends, said invention, then, consists of the means hereinafter fully described and particularly pointed out in the claims.

The annexed drawing and the following description set forth in detail certain mechanism embodying the invention, such disclosed means constituting, however, but one of various mechanical forms in which the principle of the invention may be used.

In said annexed drawing Fig. 1 is a vertical sectional view through my improved fixture and a globe; and Figs. 2 and 3 are diagrammatic views showing the holder before and after being weighted to connect an unevenly weighted globe.

The present fixture comprises a globe holder 1 of inverted cup shaped form, having a globe receiving flange 2 at the lower edge and provided with globe securing screws 3 or like means for securing the globe in place. At the top the holder is supplied with an eye 4 held in place by the usual nut .5 and the supporting chain 6 is attached to the eye in the usual manner. The chain itself is made up of a series of oblong links 7, which are formed into shape, each link being bent to shape out of a single piece of metal, but the butt joint 8 between the ends Serial No. 645,219.

of each link is not at the center of the end curve but at one side of the curve leaving a hook 10011 the split end of the link to be engaged by either a similar hook on the next link or by the other closed end of the link. There the ends butt together in the middle of the curved end of the link the other link acts as a wedge or cam to spread the ends and allows the links to come apart. This action is particularly liable to happen in supporting heavy globes. The weighting device consists of a cylindrical member 15 which fits snugly within the globe holder, the top edge of the member 15 being secured to the interior of the holder by screws 16 or the like, or it may be welded or otherwise attached. The lower edge 17 of the member 15 is turned outwardly and upwardly, forming an annular trough 18 and the upturned edge fits underneath the substantially horizontal portion of the holder adjacent the globe receiving flange 2, thus forming a closed annular channel adjacent the outer edge of the holder. This member 15 is also provided with a series of flutes or ribs 20 extending into the interior, and forming the interior of the channel into a series of pockets. A knockout plug 21 is formed in the globe holder over the annular channel and through this opening shot 22, or like weighting material, may be poured into the channel, either before or after the fixture is set up. In Fig. 1 shot is shown as being placed in the channel and concentrated at the left hand portion as shown in looking at the figure. In Fig. 2 a holder and globe is diagrammatically illustrated, the holder and globe hanging at an angle a to the vertical, as illustrated by the lines w-a2 and y-3 while Fig. 3 illustrates the same globe and holder with shot placed in the channel at the right to overcome the original incorrect weighting to bring the holder and globe back to the correct vertical position.

The inner surface of the member 15, that is the surface seen when looking at the interiOr of the holder, may be polished to provide a reflecting surface and the flutes or ribs hold the shot in the pockets and prevent accidental movement thereof by slight tipping, making it easy to obtain the correct weighting of the holder.

In ordinary use the holder is supplied empty and shot or weightmg material will be placed therein, only in such cases as are found necessary. The knockout plug may easily be bent back to receive the shot and may then be bent into place to close the opening.

By the present construction the interior of the holder may be given a reflecting surface and is enhanced in appearance. Globes may be used which would otherwise be classed as defective and the fixture and globe may be hung vertically with a minimum of effort. Globe changes may be compensated by adding additional weight or by changing the distribution of the weight in the channel. The exterior of the holder remains unchanged, except for the single plug opening which is substantially invisible.

Other modes of applying the principle of my invention may be employed instead of the one explained, change being made as regards the mechanism herein disclosed, provided the means stated by any of the following claims or the equivalent of such stated means be employed.

I therefore particularly point out and distinctly claim as my invention 1. In a lighting fixture, the combination of a globe holder open at the bottom, a

member secured within said holder and forming an annular channel, an opening in said holder above such channel, whereby weighting material may be inserted in said channel.

2. In a lighting fixture, the combination of a globe holder open at the bottom, a member secured within said holder and forming an annular channel, said member being provided with spaced ribs, and an opening in said holder above such channel for the in sertion of weighting material therein.

3. In a lighting fixture, the combination of a globe holder of inverted cup shape having a globe receiving flange, a member mounted within said holder and forming an annular channel adjacent said flange, and an opening in said holder above such channel for the insertion of weighting material therein.

4. In a lighting fixture, the combination of a globe holder of inverted cup shape having a globe receiving flange, a. member mounted within said holder and forming an annular channel adjacent said flange, said member being provided with a series of ribs, and an opening in said holder above such channel for the insertion of weighting material therein.

5. In a lighting fixture, the combination of a globe holder of inverted cup shape having a globe receiving flange, a member mounted within said holder and forming an annular channel adjacent said flange, said member being provided with a series of ribs and having its outer surface polished to act as a reflector, and an opening in said holder above such channel for the insertion of weighting material therein.
